摘要:

目前的新闻数据集只关注新闻的文本特征,很少利用图像的特征,排除了许多用于新闻分类的基本特征。在本文中,我们提出了一个新的数据集,N24新闻,这是从纽约时报产生的24个类别,并包含在每个新闻的文本和图像信息。我们使用多任务的多模态方法和实验结果表明,多模态新闻分类性能优于纯文本新闻分类。根据文本的长度,分类准确率最高可提高8.11%。我们的研究揭示了多模态分类器和其子分类器的性能之间的关系,以及将多模态应用于新闻分类时可能的改进。N24新闻在多模态新闻研究中具有巨大的潜力。

英文摘要:

Current news datasets merely focus on text features on the news and rarely leverage the feature of images, excluding numerous essential features for news classification. In this paper, we propose a new dataset, N24News, which is generated from New York Times with 24 categories and contains both text and image information in each news. We use a multitask multimodal method and the experimental results show multimodal news classification performs better than text-only news classification. Depending on the length of the text, the classification accuracy can be increased by up to 8.11%. Our research reveals the relationship between the performance of a multimodal classifier and its sub-classifiers, and also the possible improvements when applying multimodal in news classification. N24News is shown to have great potential to prompt the multimodal news studies.
